Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 12; Mjukstrålar i analfenan: 8; Ryggkotor: 34. Shares with its most similar congeners Psilorhynchus amplicephalus, Psilorhynchus balitora and Psilorhynchus nepalensis a low number of rays in the upper caudal fin
lobe and in terms of general appearance. Diagnosed from these species and all other congeners by presence of sexually dimorphic pectoral fins, which are much longer in males than in females (vs. pectoral fins of both sexes equal in size or only slightly longer in males). Differs further from Psilorhynchus amplicephalus, Psilorhynchus balitora and Psilorhynchus nepalensis by its higher number of principal rays in the lower caudal-fin lobe (9 vs. 8 in Psilorhynchus amplicephalus and Psilorhynchus nepalensis, 7-8 in Psilorhynchus balitora), and from Psilorhynchus balitora by the absence (vs. presence) of scales from the midventral region between pectoral fins. Can be easily separated from three other congeners (Psilorhynchus breviminor, Psilorhynchus robustus, and the sympatric Psilorhynchus melissa) in Myanmar by having lower number of principal rays in the upper caudal-fin lobe (9 vs. 10) (Ref. 85100).
Body shape (shape guide): elongated.
Collected together with Akysis vespertinus, Psilorhynchus melissa and other new fish species from the headwaters of Ann Chaung drainage in Myanmar (Ref. 85100).
